The answer is dryed air (0,024 W/m.K).
cork, the air inside the cork isolates. (air when trapped inside a vesicle is a great isolator)
Rubber, due to polymeric nature.
plastic as its the worst electrical conductor
Not likely unless it is carrying electricity or coming out of the muzzle of a gun. One of our company's products is a copper IUD (Intra-uterine device). In that application, the copper wire slowly dissolves and produces a pharmacological effect so it is regulated as a drug. Otherwise, the worst effect is that copper will turn your skin green.
Styrofoam because it has a thick layer and is a good insulator.Paper and plastic are could alternatives but Styrofoam would work better, therefore glass would be the worst one to use because it would only keep it warm for a couple of minutes.

Rubber, due to polymeric nature.
tin, copper, rubber, air, water
Copper is a good conductor, that's why it is used to make electrical wire.
plastic as its the worst electrical conductor
either copper or aluminum, but definitely not wood. copper is the best conductor of heat, aluminum comes second. Wood is the worst conductor as it doesn't contain free electrons that move around and transfer heat energy. Hope it helps!
The last time I checked the worst conductor of electricity is rubber.
The worst conductor would be rubber and the best metallic conductor would be silver
The worst metal conductor of heat is very probable bismuth with a thermal conductivity of 7,97 W/m.K.-------------------------------------------------------------------------------------------Aluminum conducts heat brilliantly, which is why it is used for most heat sinks and cooling fins, along with copper, another brilliant conductor of heat.--------------------------------------------------------------
Aluminium is a good conductor of heat.
No.
Since most water is carried to houses through copper pipes, yeah.
